Definitions

As used in the present specification, the following words and phrasesare generally intended to have the meanings as set forth below, exceptto the extent that the context in which they are used indicatesotherwise.

The term “complex” refers to a formation resulting from the interactionbetween Compound I and another molecule.

The term “solvate” refers to a complex formed by combining Compound Iand a solvent.

The term “co-crystal” refers to a crystalline material formed bycombining Compound I, or any Formula disclosed herein and one or moreco-crystal formers (i.e., a molecule, ion or atom). In certaininstances, co-crystals may have improved properties as compared to theparent form (i.e., the free molecule, zwitterion, etc.) or a salt of theparent compound. Improved properties can be increased solubility,increased dissolution, increased bioavailability, increased doseresponse, decreased hygroscopicity, a crystalline form of a normallyamorphous compound, a crystalline form of a difficult to salt orunsaltable compound, decreased form diversity, more desired morphology,and the like. Methods for making and characterizing co-crystals areknown to those of skill in the art.

Any formula or structure given herein, including Compound I, is alsointended to represent unlabeled forms as well as isotopically labeledforms of the compounds. Isotopically labeled compounds have structuresdepicted by the formulae given herein except that one or more atoms arereplaced by an atom having a selected atomic mass or mass number.Examples of isotopes that can be incorporated into compounds of thedisclosure include isotopes of hydrogen, carbon, nitrogen, oxygen,phosphorous, fluorine and chlorine, such as, but not limited to ²H(deuterium, D), ³H (tritium), ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸F, ³¹P, ³²P, ³⁵S,³⁶Cl and ¹²⁵I. Various isotopically labeled compounds of the presentdisclosure, for example those into which isotopes such as ³H, ¹³C and¹⁴C are incorporated. Such isotopically labeled compounds may be usefulin metabolic studies, reaction kinetic studies, detection or imagingtechniques, such as positron emission tomography (PET) or single-photonemission computed tomography (SPECT) including drug or substrate tissuedistribution assays or in radioactive treatment of patients.

The disclosure also includes Compound I in which from 1 to “n” hydrogensattached to a carbon atom is/are replaced by deuterium, in which n isthe number of hydrogens in the molecule. Such compounds exhibitincreased resistance to metabolism and are thus useful for increasingthe half-life of Compound I when administered to a mammal. See, forexample, Foster, “Deuterium Isotope Effects in Studies of DrugMetabolism”, Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compoundsare synthesized by means well known in the art, for example by employingstarting materials in which one or more hydrogen atoms have beenreplaced by deuterium.

Deuterium labeled or substituted compounds of the disclosure may haveimproved DMPK (drug metabolism and pharmacokinetics) properties,relating to distribution, metabolism and excretion (ADME). Substitutionwith heavier isotopes such as deuterium may afford certain therapeuticadvantages resulting from greater metabolic stability, for exampleincreased in vivo half-life or reduced dosage requirements. An ¹⁸Flabeled compound may be useful for PET or SPECT studies. Isotopicallylabeled compounds of this disclosure and prodrugs thereof can generallybe prepared by carrying out the procedures disclosed in the schemes orin the examples and preparations described below by substituting areadily available isotopically labeled reagent for a non-isotopicallylabeled reagent. Further, substitution with heavier isotopes,particularly deuterium (i.e., ²H or D) may afford certain therapeuticadvantages resulting from greater metabolic stability, for exampleincreased in vivo half-life or reduced dosage requirements or animprovement in therapeutic index. It is understood that deuterium inthis context is regarded as a substituent in Compound I.

The concentration of such a heavier isotope, specifically deuterium, maybe defined by an isotopic enrichment factor. In the compounds of thisdisclosure any atom not specifically designated as a particular isotopeis meant to represent any stable isotope of that atom. Unless otherwisestated, when a position is designated specifically as “H” or “hydrogen”,the position is understood to have hydrogen at its natural abundanceisotopic composition. Accordingly, in the compounds of this disclosureany atom specifically designated as a deuterium (D) is meant torepresent deuterium.

The term “therapeutically effective amount” refers to an amount that issufficient to effect treatment, as defined below, when administered to amammal in need of such treatment. The therapeutically effective amountwill vary depending upon the subject being treated, the weight and ageof the subject, the severity of the disease condition, the manner ofadministration and the like, which can readily be determined by one ofordinary skill in the art.

In addition, abbreviations as used herein have respective meanings asfollows:

EXAMPLES Example 1. Stable Form Screens

Compound I can be synthesized according to the methods described in WO2013/075029 or U.S. Provisional Application No. 62/010,813 (filedconcurrently herewith and titled “Processes for Preparing AntiviralCompounds”), both of which are incorporated by reference in theirentirety. A stable form screen was performed in an attempt to obtain acrystalline form of Compound I using 10 to 20 volumes of the primarysolvent and 5 to 10 volumes of anti-solvent (if applicable).

1.1 Compound I Form I

An additional stable form screen was performed using the same procedureas described above but included a crystalline intermediate (Compound IIshown below) as seeds.

Compound II can be synthesized according to the methods described in WO2013/075029 or U.S. Provisional Application No. 62/010,813. Needle-likeparticles were formed in butyronitrile, propionitrile, MEK/toluene,MEK/IPE and 2-pentanone/toluene. XRPD patterns of the wet solids weremostly consistent with each other with minor shifting in the peaks. Thenew form is named Compound I Form I, which is believed to beisostructural channel solvates with the respective solvents. After airdrying all solids afforded amorphous XRPD patterns.

Another stable form screen was performed using carbon (Darco G-60)treated Compound I, solvents, antisolvent (diisopropyl ether (IPE)), andseeds of Compound I Form I. This screen afforded crystalline solids fromadditional solvents as summarized in Table 1. The XRPD patterns of allof these solvates are consistent with Form I. The solvates were observedto convert to amorphous solids after drying. The XRPD patterns ofCompound I were obtained in the experimental setting as follows: 45 kV,40 mA, Kα1=1.5406 Å, scan range 2-40°, step size 0.0167°, counting time:15.875 s.

The crystallinity of Compound I Form I can be improved by using abutyronitrile/butyl ether (BN/BE) mixture according to the followingprocedure.

The crystallization experiment was started with 40 to 75 mg Compound Iin 1.1 to 3.0 mL of a BN/BE in a ratio of 7:4 (anhydrous solvents). Thesample was held at RT over P₂O₅ for 23 days without agitation, andcrystals formed in the solution. Afterwards, the liquid phase wasreplaced with butyl ether and the solids were obtained by centrifuge.These solids, corresponding to Compound I Form I, were used for thesubsequent step as seed.

Purified Compound I (709.8 mg) was prepared from reflux of ethanolsolution with Darco G-60 and was added to a new vial via a filter. Whilestirring, 7 mL of anhydrous butyronitrile (BN) was added. A clear orangesolution was obtained. While stirring, 4 mL of anhydrous butyl ether(BE) was added slowly. To the solution was added 7.7 mg of Compound IForm I (from previous BN:BE crystallization experiment) as seed. Thesolution became cloudy and the seeds did not dissolve. The sample wasstirred for ˜10 minutes before the agitation was stopped. The vial wascapped and placed into ajar with some P₂O₅ solids at room temperature.After 6 days, a thin layer of bright yellow precipitate was observed onthe wall and the bottom of the vial. The liquid phase was withdrawn and3 mL of anhydrous butyl ether was added. Solids were scraped down with aspatula from the vial. The suspension was heated to about 30° C. forover half hour period and was held for ˜1 hour before cooling to 20° C.at about 0.1° C./min (without agitation). The sample was stored in ajarwith P₂O₅ solids for 5 days. The sample was vacuum filtered using 0.22μm nylon filter, washed with 2×200 μL of anhydrous butyl ether, and airdried under reduced pressure for about 5 minutes.

XRPD analysis of the sample showed good very sharp peaks as shown inFIG. 1. The XRPD analysis setting was as follows: 45 kV, 40 mA,Kα1=1.5406 Å, scan range 1-40°, step size 0.0167°, counting time: 36.83s. The characteristic peaks of crystalline Compound I Form I include:2.9, 3.6, 4.8, 5.2, 6.0°2θ (FIG. 1). The XRPD pattern of Form I wassuccessfully indexed, indicating that Form I is composed primarily of asingle crystalline phase. Extremely large unit cell volume containing upto ˜60 API molecules in the unit cell was observed. The amorphous haloobserved in the XRPD pattern could be a result of the size of the unitcell. Butyl ether stoichiometry could not be estimated. Two alternativeindexing solutions were found: monoclinic and orthorhombic.

DSC and TGA data confirmed that Form I is a solvated form. DSC shows abroad endotherm with onset at 109° C. and small endotherm with onset at177° C. (FIG. 2). TGA shows 22% weight loss below 150° C. (FIG. 3).

Example 2. Compound I Salt/Co-Crystal Screens

Salt/co-crystal screens afforded four crystalline salts or complexeswith hydrochloric acid, phosphoric acid, L-tartaric acid, andhydrobromic acid. Among those salts, Compound I bis-HCl has severalcrystalline and mesophase forms, Compound I Phosphate has eight uniqueXRPD patterns, Compound I L-tartrate has two unique XRPD patterns, andCompound I bis-HBr has one crystalline form.

2.1 Compound I Bis-HCl

The mesophase solids were obtained from acetonitrile during saltformation using 10 volumes of solvent and 2 equivalents of HCl.Re-slurry of this mesophase material in acetone (10 volumes) affordedplate crystals. However, XRPD showed that although the solids fromacetone (FIG. 44) had more peaks in the XRPD pattern than those fromacetonitrile, the intensity and number of the peaks do not meet theexpectation for crystals, and it is therefore still considered amesophase. These XRPD patterns were obtained in the experimental settingas follows: 45 kV, 40 mA, Kα1=1.5406 Å, scan range 2-40°, step size0.0084°, counting time: 8.26 s. The DSC analysis of Compound I bis-HClfrom acetone was conducted using 10° C./min heating rate over the rangeof 25-400° C. and showed multiple endothermic events (FIG. 45). The TGAdata of Compound I bis-HCl from acetone were obtained using 10° C./minheating rate over the range of 25-400° C. and showed 3.6% weight lossbelow 60° C. and 6.7% weight loss at 170-220° C. (FIG. 46).

The stable form screen of Compound I bis-HCl was performed using 20solvents (5-10 volumes) in an attempt to discover all crystalline forms,as summarized in Table 2. Four crystalline solvates were discovered inthe slurries, which utilized alcohols such as methanol, ethanol and1-propanol. With ethanol, the initial precipitation was Compound Ibis-HCl Form III solids; after stirring for two weeks, the solids becameCompound I bis-HCl Form V. The shapes of these crystals appeared asneedles, shown in FIG. 47. After vacuum drying, these solvates lostsolvents easily and changed to Compound I bis-HCl Form VI. As adesolvated form, Compound I bis-HCl Form VI absorbs water quickly whenin contact with air. For example, Compound I bis-HCl Form VI contains8.8% water by KF after drying the methanol solvate and contains 5.2%water after drying the ethanol solvate. Each form was characterized byXRPD, DSC and TGA (FIGS. 4-19). TGA and DSC analysis were conductedafter the samples were dried at room temperature in vacuum oven for 1hour.
